It’s not good comedy when the people you’re making fun of aren’t laughing too.

This is where I draw the line between comedians like Dave Chappelle and, say, Jimmy Carr. It's fair to say Jimmy Carr isn't everybody's cup of tea, because his jokes can be really dark and really offensive - but he pokes fun at everybody, not just one specific group, and he can take it when someone pokes back.

When a comedian makes fun of everybody, and sees the humour when others make fun of them, it gives the sense there's no real hatred or malice there, and that makes it better comedy than when the jokes come from a place of real bigotry.
